It's a troll theory. The series ended with no one getting together which left the shippers in shambles. Then trolls added fuel to the fire by claiming that, if you really squint at the final group shot of 1-A it looks like Bakugou is grabbing Ochako's ass.
But can we all agree that if Deku didn't get OFA and the Hero Course, he no doubt would've gotten into the Support Course, and Mei would've been his confidant and most probably love interest?
